Natural gas production must increase in Mexico to sustain growing demand. Some of the necessary work is already taking place. About half of Mexico's electrical grid capacity additions between 2016 and 2018 came from natural gas. Furthermore, SENER forecasts that Mexican natural gas production will nearly double by 2030.

In thin or discontinuous coal seams, mudstone with low permeability can hinder overall coal seam permeability. A medium permeability range (1 × 10 –3 –5 × 10 –3 μm 2) is favorable for the replacement of CBM by CO 2. Deep coal seams should have a minimum permeability of 0.01 × 10 –3 μm 2 to ensure effective CO 2 injection.
